You didn't properly specify the x-axis coordinates in your call to lines(): plot(density(x)) lines(x,dlnorm(x, -.1348, .1911), col='red') points(x,dlnorm(x, -.1348, .1911), col='blue') curve(dlnorm(x, -.1348, .1911), col='green',add=T) On Sun, Apr 5, 2009 at 6:40 AM, Bernardo Rangel Tura wrote:

Here is what I get from using 'fitdistr' in R to fit to a lognormal. The resulting density plot from the distribution seems to be a reason match to the data. > x <- scan() 1: 0.80010 0.72299 0.69893 0.99597 0.89200 0.69312 0.73613 1.13559 9: 0.85009 0.85804 0.73324 1.04826 0.84002 14: 1.76330 0.71
